ROTARY STEAM-ENGINE.

Application filed March 13, 1916.

To all whom it may concern Be it known that I, VAN EVERY EDWARDS, acitizen of the United States, a. resident of Decatur, in the county ofMacon and State of Illinois, have invented new and useful Improvementsin Rotary'Steam-Engines, of which the following is a specification.

My invention relates to improvements in steam engines and the principalobject lsto provide a mechanism of that character which will develophigh power and efficiency with a minimum consumption of steam. j a I Tothe accomplishment of the foregoing and such other objects as mayhereinafter appear, my invention consists in the combination,construction and arrangement of parts hereinafter described and thensought to be defined in the appended claims, reference being had to theings forming a. part hereof, and which show merely for the purpose ofillustrative disclosure, a preferred embodiment'of my in vention, itbeing understood that various changes may be made in practice within thescope of the claims without digressing from my inventive idea.

In the drawings: Figure 1 representsan elevation of a plurality ofengines constructed according to my invention, one of. the motors beingshown in section; Fig. 2 is aside elevation plate being removed, andparts being shown in section to facilitate disclosure.

Referring now to the drawings, the numeral l designates suitablesupporting memsecured to a concrete foundation or in any other suitablemanner. On these supporting members are mounted. the casings oftheengine and also the supports for the shaft. This shaft is designatedby the reference character 2 having the bearings 3 on supports 1 and ispreferably provided at an intermediate point with the clutch mechanism5, whereby the two parts of the shaft may be coupled or disconnected asdesired.

6 and 7 designate suitable fly wheels, 8 a governor driven by means of.thebelt and pulley arrangement 9.

10 indicates a steam header having the supply pipes 11 leading into theseparate engines.

Each engine or motor includes the casing 12 which is bolted to thesupports and which Specificationof Letters Patent.

accompanying drawof one of the motors, the cover Patented Jan. 9, 1917.Serial No. 83,877.

has the cylindrical compartment 13 therein. In this compartment revolvesthe rotor 14- which is keyed or otherwise secured to the shaft 2, theshaft 2 running loosely within the casing 12. The casing 12 is providedwith the side cover plate15 secured thereto by means of bolts 16, asshown. packing members 15 are provided between the wall of the casingand sides of the rotor so as to provent the escape of steam.

Referring now particularly to Fi 2, the numeral 17 designates the inletconnection and 18 theexhaust connection. On the in side face of thecasing I provide a plurality of dove-tailed recesses 19, one of which isarranged between the inlet and exhaust connections. lVIounted in thesedove-tailed recesses are the holding and guiding members 20 which havethe dove-tailed portion 21 to fit the dove-tailed recess and also havingthe laterally extending wind portions 22 which rest against the insideof the casing. Adjustably mounted in each holding and guiding member 20the pressure block 28, being located in the recess 24 in the holding andguiding member and adjustable by means of the screw member 25 having thesquared head 26. This screw member has the loose connection 27 with thepressure block soas to permitits rotation therein.

The rotor is provided on its peripheral face with the plurality ofbuckets or recesses 28 which are formed as shown, having the abrupt edge29 and the inclined face 30 leading to a feather edge. These buckets orrecesses are arranged close together about the face of the rotor. V

The steam is lubricated before entering the engine so that all thebearings are thereby lubricated.

As shown in Fig. 1, I can use both high and low speed engines which maybe coupled to work together or separately, according to workingconditions. The governor controls or regulates the admission of steam.The

rotor will flow in oil, thereby lubricating the packing rings about thesides thereof.

he operation of this mechanism is as follows: The pressure blocks withthe exception of the one between the inlet and exhaust Suitable orrron.

to restrict the circuit of the steam so that more and more of its forceis exerted against the buckets 28 and particularly against the abruptface or wall 29 thereof, thereby gradually increasing the speed ofrotation of the rotor. ing under the pressure blocks and expands onpassing each pressure block. The buckets are arranged so that when oneis under a pressure block, the supply of steam thereto being cut OK, thenext one will be subjected to the steam from the inlet connection. Thisis true in connection with all of the pressure blocks so that a maximumefficiency in operation is obtained.

W hat I claim is:

1. In combination in a rotary engine, a cylindrical casing, a rotormounted therein, packing between the sides of the rotor and the casing,said casing having inlet and exhaust connections, a plurality ofpressure blocks adjustably mounted in said casing and adapted to bemoved toward and from the rotor, one being located between the inletand. exhaust connection, said rotor having a plurality of buckets orsockets provided in the face thereof.

2. In combination in a rotary engine, a cylindrical casing immovablymounted, a rotor mounted therein, packing between the sides of the rotorand easing, saidrotorbcing provided with a plurality of recesses orbuckets on its face, said casing having inlet and exhaust connections, aplurality of pressure blocks located at intervals about the casing, onebeing located between the inlet and exhaust connections.

3. In combination in a rotary engine, a cylindrical casing immovablymounted, a rotor mounted therein, packing between the sides of the rotorand easing, said rotor being provided with a plurality of recesses orbuckets on its face, said casing having inlet and exhaust connections, aplurality of pressure blocks located at intervals about the casing, onebeing located between the inlet and exhaust connections, and means foradjusting the pressure blocks to and from the rotor.
